Copy the existing files to the "standard" file folder. Or use a different folder if you prefer. The main this is: do not attempt to attach the only copy of the files. Reason: attach can change the contents of the file, and a failed attach could make it (almost) impossible to ever attach the files again. Thus, don't risk it on the original files, only on a copy. If the attach fails, you can copy the files again and re-try.
As to specific mechanics, open SSMS an issue a CREATE DATABASE ... FOR ATTACH command. Don't use the gui.
CREATE DATABASE [db_name] --<<--use any db_name you want
ON PRIMARY ( NAME = db_name_data, MAXSIZE = UNLIMITED, FILEGROWTH = 10MB,
FILENAME = 'c:\Program Files (x86)\...\HEALSExamsSQL.mdf' )
LOG ON ( NAME = db_name_log, MAXSIZE = UNLIMITED, FILEGROWTH = 2MB,
FILENAME = 'c:\...\HEALSExams_log.ldf' )
